WATER-CLOSET.

Specication of Letters Patent.

Patented Aug. 4, 1914.

Application led August 3, 1908. Serial No. 446,503.

T0 all whom it may concern Be it known that I, EARL G. WA'rRoUs, acitizen of the United States, residing at Chicago, in the State ofIllinois, have invented a certain new and useful Improvement inlater-Closets, of which the following is a description, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to what are known as seat-actuated closed-tankclosets, being closets in which the depression of the seat opens a valvewhich admits the 'water supply to a closed tank, which fills with waterwhile the seat is depressed, and then discharges into the closet whenthe pressure on the seat is removed.

It has for its principal object an improved construction, arrangementand operation of the valves which control the admission of the watersupply to the closed tank and its subsequent release and dischargetherefrom.

In the accompanying drawings Figure l is a middle vertical section ofthe rear portion of the closet and the valve casing and the valvessupported thereon; Fig. 2 a top plan view of the parts shown in Fig. 1;Fig. 3 a cross sectional detail approximately on the line 3 3 of Fig. lwith some of the interior parts left in elevation; and Fig. 4i a crosssectional detail on the line 4-4 of Fig. l.

The same letters of reference are used to indicate identical parts inthe several views.

As shown in Fig. 1, the closet bowl A is provided in its upper rearportion with a chamber B which communicates with the flushing rim C ofthe bowl by ports a, and directly with the bowl by ports b, and isprovided in its top with a central opening D, which in the presentinstance is approximately elliptical in shape. The top of the chamber Bconstitutes the seat-shelf of the closet bowl, and upon it rests a metalcasing E having an opening in its bottom coincident with the opening Din the top of the chamber B, and secured to the latter and the bowl ofthe closet by the bolts F shown in Fig. 3. A packing ring seated in agroove formed in the bottom of the casing E around the opening thereinsecures a tight joint between the bottom of the easing and the top ofthe bowl. At its rear end the easing E is provided ywith a pipeconnection G for the water supply pipe, while the upper side of thecaslng 1s provided with a connection H for the lower end of the pipewhich leads upward to the closed tank (not shown) supported in the usualposition above the closet.

A chamber J formed in the rear portion of the casing E, in oper.communication with the connection H and pipe leading to the tank,communicates with the water supply through a central opening K in itsrear wall, and with the interior of the main portion of the casing E andthe chamber D through a coincident but larger opening L in its frontwall. The opening K in the rear wall of the chamber is controlled by avalve 0, and that in the front wall by a valve P, opening in oppositedirections and both carried by the same valve stem Q. The front end ofthis valve stem has its support and bearing in a plug R screwed into anopening in the front wall of the casing E, while its rear end issupported and guided by a disk or flange S snugly fitting within thepipe connection G. This disk or flange, which is provided withperforations or peripheral notches to permit the free passage of thewater, is in the present instance formed upon a short supplemental valvestem S seated in a bore in the rear end of the main valve stem Q andhaving a conical front end whose point alone bears against the endwallet the bore in the valve stem Q, for a nrpose hereinafter described.The valve 8 is secured upon the stem S. A coiled spring T bearingagainst the outer side of the flange S and confined within a housing Ucoupled to the connection G by a nut U serves to press all of the partsforward and yieldingly hold the valve O against its seat and the valve Paway from its seat. When, however, the valve stern and valves are forcedrearward the valve P will be closed and the valve O opened, and waterwill be permitted to pass from the supply pipe through the chamber J andpipe connection H and pipe to the tank, filling the latter' to the limitpermitted by the air in the tank. When the valve stem and valves arethereafter released the spring T will restore them to normal position,closing the valve O and cutting 0H the water supply, and opening thevalve P and permitting the tank to discharge its contents through theopening L into the chamber B, and thence to the closet bowl through theports a and b, and through a` suitable connection to the jet of thecloset, if the latter be of a character employing a jet.

The valve stem Q is operated, to open and close the valves 0 and P', inthe manner and for the purpose described, by a connection with thecloset seat V, the rearwardly and inwardly extended hinges `W of whichpass through stuing boxes KX in the opposite sides ot the casing E,Figs. 3 and 4f, and their inner endsprojecting within said casing, aresquared as shown in Fig. l and have secured upon them a hub Y providedwith a pair of depending arms Z Z'embracing a sleeve or hub Q securedupon the valve stem Q, as best shown in Pig. 3. The lower extremities otthe arms Z Z project in front of lateral studs or projections Zl Z uponthe sleeve or hub Q', shown in Pigs. 1 and 3.

ln the normal position ot the parts the seat V is slightly elevated, asin Fig. l; and when it is depressed-upon the closet bowl the lower endsot the arms Z Z are swung rearward, carrying the valve stem and valveswith them, and closing the valve P and opening the valve 0. rPhe tank isthereupon filled with water, and when the pressure upon the seat isrelieved the spring T restores the parts to normal position, closing thevalve 0, and opening the valve P and discharging the contents ot thetank into the closet.

P or the purpose of permitting an adjustment of the parts'which willcause the valve P to come to rest upon its seat at the instant thecloset seat comes to rest upon the closet bowl, the flanged hub orsleeve Q is adjustably mounted upon the valve stem Q by a threadedengagement therewith. Upon unscrewing and removing the plug R whichsupports the irontI end ot the valve stem, a screw-driver may beinserted through the opening in the 'front wall of' the casing E, fromwhich such plug has been removed, and engaged with a nick in the frontend of the valve stem, land the latter be turned to adjust the hub Qforward or backward upon the stem, to bring about the proper relationbetween the movements dof the valve P and closet seat. The provision otthe supplemental valve stem S tor the valve Q enables the latter to bereadily removed, for inspect-ion and repairs, without removing the valvestern Q and valve P; while the pointed bearing orv the front end of thestem S against the end ot the bore in the stem Q relieves the frictionbetween the parts and enables the stem Q to be easily moved, in themanner and for the purpose above described, notwithstanding the strongpressure of the spring T.

The seat hinges W W terminate at their forward ends in horizontal platesW W secured to the top ot the seat V by screws, and in vertical plateslllf2 WZ secured in like manner to the rear edge ot the seat and Ahavingan overlapping joint K as shown. IThis nineties ing the valve Qcooperating with the opening K, the spring 'P operating to press thevalves and valve stems forward, and the seat lf hinged to the casing Eand operatively connected to the valve stem Q to torce the same and thevalves 0 and P rearward when the seat is depressed; substantially asdescribed.

2. ln a water closet of the character described, the casing E having thepipe connections Gr and H and the chamber J having the openings K and Lin its opposite walls, the threaded valve stem Q having its front endsupported and guided in thel plug R in the front wall of the casing l2,the hub Q threaded upon the valve stem Q, the hinged seat V, anoperative connection between said. seat and the hub Q upon the valvestem to cause the latter to be forced rearwardly when the seat isdepressed, the

coiled spring 'll pressing the valve stem and guided at its trent end inthe screw plug R, the hub Q threaded upon said valve stem, the seat Vhaving its hinges W W journaled in the, casing E, and. the hub Y mountedon said hinges and provided with the depending arms Z cooperating withthe hub Q to torce the latter and the valve stern rearward when the seatis depressed; substantially as described.
